this is a new deployment, so sadly i cant testify that everything works. hw is:
SuperServer 6028U-TR4T+
Intel(R) Xeon(R) CPU E5-2690 v3 @ 2.60GHz
64gb ecc. couple of 120gb ssds for boot, couple of 512gb nvme for cache on the supermicro card. and a bunch of 6tb sas drives.
the server is not doing anything special, only SMB (multichannel) nothing else. connected to a 10gbe switch, 3 machines are directly connected (that is, each card is on a different subnet, so each machine connected to a nic by its ip only)
user reports, this usually happens when the internet goes out (that makes no sense lol)
also, the network still works, i can ping the ipmi, but the console does not responds to keyboard, i can even mount an ISO and i see no activity from the OS.
none of the interfaces (besides the IPMI) replies to ping when this happens.
